RHA, FTA. CPT and SMMT Expiry date N/A Supersedes Memos N/A
Purpose: The purpose of this memo is to define the procedure for Delayed Prohibition Issue requirements applicable when an illuminated ABS Malfunction Indicator Lamp (MIL) is found
Process Users: Vehicle Examiners
Initiating Inputs: An illuminated ABS MIL is found at roadside inspection
Outputs: To ensure VOSA applies a consistent procedure in accordance with the Road Vehicles (Construction and Use) Regulations 1986 Regulation 18, that does not compromise road safety
Procedure — General Rules: - C&U Regulation 18(1A) & (1B) gives dispensation for the sanction level applied for an ABS MIL defect if the defect occurs “during the journey or is being driven to a place where the ABS is to undergo repair” - It is acknowledged that it is not possible for an examiner to independently determine whether a MIL has become illuminated during a journey, at the start of which the ABS system was functioning correctly - This procedure therefore shows the process to be used in order for the Examiner to decide, to the best of his ability using the evidence supplied, whether or not the dispensation (as specified by C&U Reg 18) can be applied to the specific circumstance in question, e.g. an illuminated ABS MIL. - This procedure applies to Anti-Lock Braking System MIL only, and not Electronic Braking System MIL - By “this journey” it is meant, the current journey which must have been started within the day. For practical purposes a day is defined as any 24 hour period that begins when a driver starts work after a daily or weekly rest. It is not a rolling period.
This Procedure applies to domestic and non-domestic vehicles Procedure: Responsibility Procedure Notes 1. Vehicle Examiner Examiner finds ABS MIL illuminated 2. Vehicle Examiner Establish if the MIL is coloured red or yellow/amber 3. Vehicle Examiner If lamp is coloured red the normal prohibition sanction level as specified by the Categorisation of Defects is applied 4.Vehicle Examiner If the ABS MIL is yellow/amber but a secondary red (Stop) warning lamp is illuminated, this must be treated the same as a red lamp 5. Vehicle Examiner If the lamp in coloured yellow/ amber the examiner will need to obtain evidence from the vehicle driver that the MIL became illuminated during this journey 6. Vehicle Examiner Evidence for 5 above must consist of the following and be available at the time of inspection: 6. (i) Walk around check sheet correctly completed indicating correctly functioning braking system The check sheet may be electronic. The check sheet may specify ‘ABS’ 6. (ii) A defect reporting log which must include date, time, location, mileage (at time of incident), details of action taken (including any rectification if applicable) Note. ‘Action taken’ must contain information such as driver checked no visible defect evident or OBD interrogation occurred and note that brake performance and operation appears to be normal. 7. Vehicle Examiner If the examiner is satisfied that, from the evidence provided, the defect occurred within the present journey, and/or the vehicle is en route to a place of repair (or a repairer is travelling to the scene) and that no other obvious braking defect is present then an Inspection Notice is to be issued Andrew Cattell Vehicle Standards Manager Heavy Vehicle Scheme Management March 2011
Shame is I never met a VOSA man who knows how the hell an ABS system works have you?
nick2008:
red lights a no no … yellow take it but inform the office in form as a defect … some times its a wire fault or system fault … ABS EBS will not effect the working system of the actual brakes
as you say abs wont effect the working of the brakes, but if I has an ebs fault that’s a defect that can effect the safe working of the brakes, infact you can end up with no brakes at all!
who ever came up with the idea of ebs should be made to explain why you have air valves that can now fail due to a broken wire!
Bking:
Mercedes and Volvo recon that an electrical “glich” will send truck system into default eg full air feed with full braking!
Lies ,dam lies and statistics.
Had systems fail and the only way to stop is via the hand valve.And not just once.
You get BS on the dash and you need to stop quick you got problems.
this is quite common, though it’s never been a problem on my fh I know of various Volvos where this fault has left the hand valve as the only way to stop

Thats as i thought, i told my planner i was unhappy to take the trailer, come into work yesterday and i’m getting it in the neck, being told unofficially ill prob get the sack for it, but if i had of taken it had an accident they would of hung me out to dry!
But they are asking you to take a vehicle on the road which has a defect and a defect which could affect the safe braking of that vehicle. How can that be right?
Let em sack you for it and then watch the £££££ come in when you take them to a tribunal!!
I’ve got a funny story that I thinks relevant to this red and yellow warning light bollox.
When I’d just started driving I was givin a renault to take to the garage at bellshill, it was displaying the red light workshop stop basically telling you not to drive it on the road.
We’ll this unit was operating normally, never mind what the computer was saying, but 1 of the guys in traffic thought it would be a good idea to give me a trailer loaded with a drop that was on the way to bellshill.
So here’s me driving along the old glasgow A road with this 27? Ton load ■■■■■■■■ myself and just my luck, Mr VOSA had set up a check point and decided it a good idea to pull my 61 plate premium over, talk about my ■■■■■■■ going 5p 10p.
So I park up switch engine off before he sees the dash etc, asks a few questions then gets me out so he can d/l data etc, takes his little machine back to his van to plug in laptop and check my hours. He then tells me the mechanic is busy right now but will check my motor over when he’s finished giving a landscaper the 200degrees about his trailer being a bulb short (blown).
I get talking to Mr VOSA who comes across as quite a nice chap lol, explain I’m new he’s asking a lot of questions about my firm and I’m bigging them up and trying to crack jokes to hide the fact I’m aware of the trouble I could be in lol.
10 mins of convo later this little hot Ms (I’d like to hope) VOSA bring my card over says everything is fine no problems and they let me go with waiting on their mechanic looking me over.
Was I right to be nervous? Lol lesson learned anyway was funny at the time.
